The flexible lock portion 50 is elongated in the direction along the plate surface of the operation portion 42 and is generally formed along the direction connecting the operation portion 42 and the shaft hole 44. The flexible lock portion 50 has a seesaw shape in which the hinge 48 described above is formed in the vicinity of the center in the longitudinal direction, and the flexible lock portion 50 approaches or moves away from the side wall of the male housing 10 with the hinge 48 as a fulcrum. It is formed so as to be able to bend and deform in the direction. A locking portion 51 that protrudes inward in the thickness direction of the lever is formed at the end of the flexible lock portion 50 on the side close to the shaft hole 44. The locking portion 51 is a groove shape extending in the front-rear direction by retracting inward to a position corresponding to the locking portion 51 on the outer side surface of the side wall of the male housing 10 in a state where the lever 12 is in the fitting position. The lever 12 is locked so as not to rotate by engaging with the latch receiving portion 52 formed in the above. On the other hand, a release portion 53 that protrudes outward in the thickness direction of the lever is formed at the end of the flexible lock portion 50 that is closer to the operation portion 42. The release portion 53 is disposed near the operation portion 42 in the region between the shaft hole 44 and the operation portion 42. By pressing the release portion 53 in a direction approaching the side wall of the male housing 10, the flexible lock portion 50 swings with the hinge 48 as a fulcrum, and the locking portion 51 of the flexible lock portion 50 is formed. The end on the other side is displaced in a direction away from the side wall of the male housing 10. As a result, the engagement between the engaging portion 51 of the lever 12 in the fitting position and the engaging receiving portion 52 of the male housing 10 is released, and the lever 12 can be rotated.

  Then, the structure of each member in the progress state of fitting operation of both the housings 10 and 11 is demonstrated. First, when both housings 10 and 11 are in the state shown in FIG. 1, the female terminal fitting 22 is inserted into the cavity 21 of the female housing 11 and locked by the lance 29, and the retainer 30 is crowned. It is double-locked with. On the other hand, the male terminal fitting 23 is inserted into the cavity 21 of the male housing 10 and is locked by the lance 29, and the retainer 30 is mounted to be double locked. The lever 12 disposed in the male housing 10 has a latching claw 47 of the temporary latching lock portion 34 engaged with the second side guide slit 33 and a stopper 43 against the outer surface of the upper wall of the male housing 10. By contacting, it is held non-rotatable at the standby position. In this state, the inlet of the cam groove 14 of the lever 12 and the side-side first guide slit 15 of the male housing 10 are aligned and opened forward, and the cam pin 13 of the female housing 11 is connected to the cam groove 14 and the side surface. It is allowed to enter the side first guide slit 15.

  Next, in a state where both the housings 10 and 11 are moved to the positions shown in FIG. 12, the cam pin 13 enters the cam groove 14 of the lever 12 and the first side guide slit 15 on the side surface of the male housing 10. At this time, the side guide ribs 16 have entered the first side guide slits 15, the upper side guide projections 17 have entered the upper side guide slits 18, and the lower side guide ribs 19 have been provided on the lower side. The guide groove 20 is entered, and the retainer side guide rib 32 further enters the side surface side second guide slit 33. In this state, the temporary locking lock portion 34 rides on the retainer side guide rib 32 and bends and deforms in a direction away from the side wall of the male housing 10, and the temporary locking claw 47 and the side side second guide slit 33 are engaged. Is released, the lever 12 can be rotated from the standby position.

  Subsequently, in the state where the lever 12 is rotated to the position shown in FIG. 13, the cam pin 13 is guided to the cam groove 14 of the lever 12 and moves in the side-side first guide slit 15 to the back, so that the male housing 10 and the female housing 11 can be displaced so as to be attracted to each other.

  Further, when the lever 12 is rotated to the position shown in FIG. 14, the housings 10 and 11 are in a properly fitted state, and the position of the lever 12 in this state is the fitting position. At this time, the engaging portion 51 of the flexible lock portion 50 of the lever 12 is engaged with the engaging receiving portion 52 of the male housing 10 so that the lever 12 is held so as not to rotate (see FIG. 16). . On the other hand, the tab piece 24 of the male terminal fitting 23 is inserted into the rectangular tube portion 25 of the female terminal fitting 22 and connected to the elastic contact piece 28, whereby the male terminal fitting 23 and the female terminal fitting are connected. 22 is electrically connected (see FIG. 15).

The female terminal fitting 22 is double-locked by being fully locked.

  Further, after the lever 12 is rotatably attached to the male housing 10, the temporary locking claw 47 of the temporary locking lock portion 34 of the lever 12 and the side-side second guide slit 33 of the male housing 10 are engaged. At the same time, the lever 12 is locked in the standby position. Subsequently, the retainer 30 is temporarily locked to the male housing 10, the male terminal fitting 23 disposed at the end of the electric wire 26 is inserted from the rear of the cavity 21, and the retainer 30 is retained by the lance 29. The male terminal fitting 23 is double locked.

  When the female housing 11 and the male housing 10 are displaced from the state shown in FIG. 1 to the state shown in FIG. 12, first, the front end portion of the female housing 11 enters the hood portion 36 of the male housing 10. When the housings 10 and 11 are further moved closer, the cam pin 13 of the female housing 11 enters the first side guide slit 15 of the male housing 10 and the cam groove 14 of the lever 12. Further, the lower surface side guide rib 19 of the female housing 11 enters the lower surface side guide groove 20 of the male housing 10. When the fitting of both the housings 10 and 11 further proceeds, the upper surface side guide protrusion 17 of the male housing 10 comes into contact with the front end edge of the hood portion 36 of the female housing 11. At this time, the front end portion of the retainer side guide rib 32 comes into contact with the temporary locking claw 47 of the temporary locking lock portion 34 of the lever 12. When a force is applied in a direction in which the housings 10 and 11 are brought closer to each other in this state, the upper wall of the hood portion 36 is bent and deformed, and the upper surface side guide protrusion 17 enters under the hood portion 36 and then the upper surface side guide slit. The two housings 10 and 11 are displaced into the state shown in FIG. At this time, the temporary locking claw 47 of the temporary locking lock portion 34 climbs over the tapered surface 35 of the retainer side guide rib 32 and rides on the retainer side guide rib 32 to bend and deform in a direction away from the side wall of the male housing 10. As a result, the engagement between the temporary locking claw 47 and the side surface side second guide slit 33 is released, and the lever 12 can be rotated.

  Subsequently, when the lever 12 is rotated in the clockwise direction in FIG. 12 while gripping the operation portion 42, the cam pin 13 is displaced along the cam groove 14 along with the rotation operation of the lever 12, and the male housing By displacing to the back side of the first side slits 15 on the side face 10, the housings 10 and 11 are pulled toward each other in the direction in which the fitting is deepened. At this time, the guide ribs 16, 19, 32 and the upper surface side guide protrusion 17 enter the corresponding guide slits 15, 18, 33 and the lower surface side guide groove 20, so that the postures of both housings 10, 11 are set. And the fitting of the two housings 10 and 11 is guided (see FIG. 13).

  When the lever 12 is further rotated, the locking portion 51 of the flexible lock portion 50 of the lever 12 comes into contact with the edge portion in the width direction on the outer side surface of the upper wall of the male housing 10 from above. Further, when the lever 12 is rotated, the locking portion 51 rides on the side wall of the male housing 10, and the flexible lock portion 50 is bent and deformed in a direction away from the side wall of the male housing 10. When the lever 12 is further rotated and displaced to the position shown in FIG. 14, the flexible lock portion 50 is restored and deformed, and the locking portion 51 is accommodated in the locking receiving portion 52 of the male housing 10. Match. Thereby, the lever 12 is locked so as not to rotate at the fitting position. At this time, when the tab piece 24 of the male terminal fitting 23 and the elastic contact piece 28 of the female terminal fitting 22 are in contact, the male terminal fitting 23 and the female terminal fitting 22 are electrically connected. .

  When the two housings 10 and 11 are separated from each other, first, the release portion 53 of the flexible lock portion 50 is pressed in a direction approaching the side wall of the male housing 10. Then, the flexible lock portion 50 swings about the hinge 48 as a fulcrum, and the end portion on the side where the locking portion 51 is formed is displaced in a direction away from the side wall of the male housing 10. Thereby, engagement with the latching | locking part 51 and the latching receiving part 52 is cancelled | released, and the lever 12 becomes rotatable. Subsequently, the lever 12 is rotated counterclockwise in FIG. 14 while the release portion 53 is pressed, whereby the cam pin 13 is guided to the cam groove 14 and the side-side first guide slit 15 is moved forward. It moves and is displaced in the direction in which both housings 10 and 11 are separated. At this time, since the release portion 53 of the lever 12 is formed at a position near the operation portion 42 in the region between the shaft hole 44 and the operation portion 42, the operator can easily rotate the lever 12. The operation can be performed. As a result, the unlocking property is improved, and the efficiency of the work of separating the connectors from each other during maintenance or the like can be improved.

  As described above, according to the present embodiment, since the locking portion 51 for holding the lever 12 in the fitting position is formed on the inner surface of the lever, the locking receiving portion 52 of the male housing 10 is formed. However, the lever 12 can be prevented from projecting outward in the thickness direction, and the male housing 10 can be downsized. Further, since the flexible lock portion 50 is formed within the thickness of the lever 12, the width on the lever 12 side can be reduced. Thereby, a connector can be reduced in size in the width direction.

  In this embodiment, the flexible lock portion 50 is formed inside the second slit 49 by cutting the annular second slit 49 in the side plate 41 of the lever 12 while leaving the hinge 48. Thereby, since the flexible lock part 50 can be arrange | positioned within the range of the existing lever 12, it can prevent that the turning locus | trajectory of the lever 12 becomes large, and can prevent the enlargement of the male housing 10.
